Technical Field

[0001] This utility model belongs to the technical field of steel wool processing equipment, specifically relating to a steel wool drawing and tightening mechanism. Background Technology

[0002] Steel wool is used for everyday tasks such as washing and scrubbing dishes, and is a frequently consumed household item. There are many types of steel wool, including one with a ring-shaped shape, such as... Figure 4 As shown, a semi-finished product, a ring-shaped steel wire mesh, is formed by continuous rolling and turning. The resulting ring-shaped semi-finished product generally has a loose structure and excessive deformation, making it inconvenient for practical use. Therefore, it usually requires subsequent tightening to reduce the outer diameter of the steel wire ball, making the structure compact and ultimately forming a finished product with a regular shape and uniform appearance. Currently, the tightening of the semi-finished ring-shaped steel wire balls is generally done manually, which is slow, inefficient, and labor-intensive. Utility Model Content
